GNU ed 0.3 review

GNU ed is a line-oriented text editor. GNU ed is used to create, display, modify and otherwise manipulate text files, both interactively and via shell scripts.

A restricted version of `ed', `red', can only edit files in the current directory and cannot execute shell commands. `ed' is the `standard' text editor in the sense that it is the original editor for Unix, and thus widely available.

What's New in This Release:
The symlink vulnerability has been fixed using the "tmpfile" function.
The signal handling for SIGINT has been fixed.
The 'c' and 'i' commands now work with address 0 (zero) as they should.
The pause mode has been removed.
Two new command line options, "--loose-exit-status" and "--verbose", have been added.
A new argument parser that replaces "getopt_long" has been added.
"configure" and "Makefile.in" have been replaced.
The manual has been updated.
An extensive code cleanup has been done.
